Es war Aufgabe der Erfindung ein Messer zu schaffen, welches einen einfachen Klingenwechsel ermöglicht, wobei das Messer eine hohe Sicherheit gewährleisten soll.It was an object of the invention to provide a knife which enables a simple blade change, the knife being intended to ensure a high level of security.

Die Aufgabe wurde gelöst mit einem Messer mit den Merkmalen des Anspruchs 1.The object was achieved with a knife with the features of claim 1.

Das Messer umfasst eine Arretierung mittels welchem der Klingenträger in der Klingenwechselposition lösbar feststellbar ist. Der Klingenträger kann unmittelbar oder mittelbar feststellbar sein. Das bedeutet, dass er z.B. auch festgestellt werden kann, indem ein mit dem Klingenträger bewegungsverbundenes Teil, z.B. ein Teil der Betätigungsvorrichtung, insbesondere die Handhabe der Betätigungsvorrichtung, arretiert wird.The knife comprises a lock by means of which the blade carrier can be detachably locked in the blade change position. The blade carrier can be directly or indirectly ascertainable. This means that it can also be determined, for example, by locking a part which is connected to the blade carrier in motion, for example a part of the actuating device, in particular the handle of the actuating device.

Die Arretierung ist z.B. zwischen einer Riegelposition und einer Löseposition bewegbar, wobei in der Riegelposition eine Bewegung des Klingenträgers mittels der Arretierung verriegelt ist und wobei in der Löseposition eine Bewegung des Klingenträgers möglich ist. Die Bewegung zwischen der Riegelposition und der Löseposition kann z.B. eine rotatorische Bewegung und / oder eine translatorische Bewegung sein.The lock is e.g. movable between a locking position and a release position, wherein in the locking position a movement of the blade carrier is locked by means of the locking device and wherein a movement of the blade carrier is possible in the release position. The movement between the latch position and the release position can e.g. a rotational movement and / or a translatory movement.

In der Riegelposition steht die Arretierung z.B. kraft- und / oder formschlüssig in Eingriff mit dem Klingenträger oder mit der Betätigungsvorrichtung. In der Riegelposition steht die Arretierung z.B. kraft- und / oder formschlüssig in Eingriff mit der Handhabe der Betätigungsvorrichtung, In der Löseposition steht die Arretierung außer Eingriff mit dem Klingenträger oder mit der Betätigungsvorrichtung.In the latch position, the lock is e.g. non-positively and / or positively in engagement with the blade carrier or with the actuating device. In the latch position, the lock is e.g. non-positively and / or positively in engagement with the handle of the actuating device, in the release position the lock is out of engagement with the blade carrier or with the actuating device.

Eine Ausführungsform ist dadurch gekennzeichnet, dass in der Schneidposition der Klingenträger oder die Betätigungsvorrichtung in Kontakt mit einem ersten Anschlag steht. Der erste Anschlag legt die Schneidposition des Klingenträgers fest. Der erste Anschlag ist z.B. zwischen einer Sperrposition und einer Freigabeposition bewegbar. In der Sperrposition ist der erste Anschlag z.B. derart in die Bewegungsbahn des Klingenträgers oder eines Elements der Betätigungsvorrichtung bewegt, dass der Klingenträger in Kontakt mit einer Anschlagfläche des ersten Anschlags steht, wenn sich der Klingenträger in der Schneidposition befindet. In der Freigabeposition ist der erste Anschlag aus der Bewegungsbahn des Klingenträgers oder des Elements der Betätigungsvorrichtung herausbewegt. Bezüglich der Merkmale hinsichtlich der Definition der Schneidposition durch den ersten Anschlag wird auch auf die DE 10 2005 049 411 verwiesen.One embodiment is characterized in that in the cutting position the blade carrier or the actuating device in Contact with a first stop. The first stop determines the cutting position of the blade holder. The first stop can be moved, for example, between a locked position and a release position. In the locked position, the first stop is moved, for example, into the movement path of the blade carrier or of an element of the actuating device such that the blade carrier is in contact with a stop surface of the first stop when the blade carrier is in the cutting position. In the release position, the first stop is moved out of the movement path of the blade carrier or the element of the actuating device. Regarding the features regarding the definition of the cutting position by the first stop, reference is also made to the DE 10 2005 049 411 directed.

Das Messer kann z.B. eine Sicherungsvorrichtung aufweisen, welche verhindert, dass der erste Anschlag in der Schneidposition des Klingenträgers in die Freigabeposition verstellt wird. Die Sicherungsvorrichtung kann z.B. erste Formschlussmittel aufweisen, die dem ersten Anschlag zugeordnet sind und zweite Formschlussmittel aufweisen, die dem Klingenträger zugeordnet sind.The knife can e.g. have a securing device which prevents the first stop in the cutting position of the blade carrier from being moved into the release position. The safety device can e.g. have first positive locking means which are assigned to the first stop and have second positive locking means which are assigned to the blade carrier.

In der Klingenwechselposition steht der Klingenträger oder die Betätigungsvorrichtung z.B. mit einem zweiten Anschlag in Kontakt. Der zweite Anschlag legt z.B. die Klingenwechselposition fest. Z.B. ist der zweite Anschlag von dem Gehäuse gebildet, wobei in der Klingenwechselposition die Handhabe mit dem zweiten Anschlag in Kontakt steht.In the blade change position, the blade carrier or the actuating device is e.g. in contact with a second stop. The second stop places e.g. the blade change position. For example, the second stop is formed by the housing, the handle being in contact with the second stop in the blade changing position.

Die Handhabe ist z.B. zwischen einer unbetätigten Position und einer betätigten Position bewegbar. In der unbetätigten Position ist der Klingenträger in der Sicherheitsposition angeordnet und in der betätigten Position ist der Klingenträger in der Schneidposition angeordnet.The handle can be moved, for example, between an unactuated position and an actuated position. In the unactuated position the blade carrier is arranged in the safety position and in the actuated position the blade carrier is arranged in the cutting position.

Z.B. ist die Handhabe über die betätigte Position hinaus in eine Endposition bewegbar, wobei in der Endposition der Klingenträger in der Klingenwechselposition angeordnet ist.For example, the handle can be moved beyond the actuated position into an end position, the blade carrier being arranged in the blade change position in the end position.

Befindet sich der erste Anschlag in der Sperrposition, kann die Handhabe z.B. lediglich zwischen der unbetätigten Position und der betätigten Position bewegt werden. In der Klingenwechselposition kann die Klinge 17 z.B. teilweise oder vollständig aus dem Gehäuse herausbewegt sein.If the first stop is in the locked position, the handle can e.g. only be moved between the unactuated position and the actuated position. In the blade change position, the blade 17 can e.g. partially or completely moved out of the housing.

Die Handhabe ist z.B. schwenkbar an dem Gehäuse gelagert. Sie kann in diesem Fall z.B. zwischen der unbetätigten Position, der betätigten Position und der Endposition schwenkbar sein. Gemäß einer Alternative kann die Handhabe zwischen der unbetätigten Position, der betätigten Position und der Endposition verschiebbar sein.The handle is e.g. pivotally mounted on the housing. In this case it can e.g. be pivotable between the unactuated position, the actuated position and the end position. According to an alternative, the handle can be displaceable between the unactuated position, the actuated position and the end position.

Aus der unbetätigten Position ist die Handhabe 13 in Richtung u1 in die betätigte Position und in die Endposition schwenkbar. Die Endposition ist dadurch gekennzeichnet, dass einer Haltefläche 23 der Handhabe 13 an einem Anschlag 21 des Gehäuses 11 anliegt und eine weitere Bewegung in Richtung u1 verhindert. Aus der Endposition ist die Handhabe 13 in Richtung u2 in die unbetätigte Position schwenkbar. Auch aus der betätigten Position ist die Handhabe in Richtung u2 in die unbetätigte Position schwenkbar.A handle 13 is part of the actuating device. It forms a swivel joint G1 with the housing and can thus be swiveled between an unactuated position and an end position. The actuated position is located between the unactuated position and the end position of the handle 13 (see Fig. 3 ). From the unactuated position, the handle 13 can be pivoted in the direction u1 into the actuated position and into the end position. The end position is characterized in that a holding surface 23 of the handle 13 bears against a stop 21 of the housing 11 and prevents further movement in the direction u1. From the end position, the handle 13 can be pivoted in the direction u2 into the unactuated position. The handle can also be swiveled in the u2 direction into the unactuated position from the actuated position.

In einer in den Fig. 1 und 2 gezeigten unbetätigten Position der Handhabe 13 befindet sich der Klingenträger 12 in der Sicherheitsposition. Durch Schwenken der Handhabe 13 in die betätigte Position gemäß Fig. 3 wird der Klingenträger 12 in die Schneidposition bewegt. Die Handhabe 13 ist von der Rückstellvorrichtung in die unbetätigte Position belastet.In one in the 1 and 2 shown unactuated position of the handle 13, the blade carrier 12 is in the safety position. By pivoting the handle 13 in the actuated position according to Fig. 3 the blade carrier 12 is moved into the cutting position. The handle 13 is loaded by the reset device in the unactuated position.

In der Schneidposition liegt der Klingenträger 12 an einem ersten Anschlag 14 an, welcher Teil eines Riegels 15 ist. Der Riegel 15 ist im vorliegenden Ausführungsbeispiel in die Richtungen w1, w2 zwischen einer Sperrposition (siehe die Fig. 1 bis 3) und einer Freigabeposition (siehe die Fig. 4 bis 6) schwenkbar an dem Gehäuse 11 gehalten. Gemäß einem alternativen Ausführungsbeispiel könnte er aber auch z.B. verschiebbar sein. Aus der Sperrposition gemäß der Fig. 1 und 2 kann der Riegel 15 in Richtung w1 in die Freigabeposition bewegt werden. Aus der Freigabeposition gemäß Fig. 6 kann der Riegel 15 in Richtung w2 in die Sperrposition bewegt werden.In the cutting position, the blade carrier 12 bears against a first stop 14, which is part of a bolt 15. The bolt 15 is in the present embodiment in the directions w1, w2 between a locking position (see the 1 to 3 ) and a release position (see the 4 to 6 ) pivotally held on the housing 11. According to an alternative embodiment, however, it could also be displaceable, for example. From the locked position according to the 1 and 2 the latch 15 can be moved in the direction w1 to the release position. From the Release position according to Fig. 6 the bolt 15 can be moved in the locking position in the direction w2.

In der Sperrposition befindet sich der erste Anschlag 14 in der Bewegungsbahn des Klingenträgers 12. Der erste Anschlag 14 legt daher die Schneidposition des Klingenträgers 12 fest, wenn er in der Sperrposition angeordnet ist. In der Freigabeposition ist der erste Anschlag 14 aus der Bewegungsbahn des Klingenträgers 12 heraus bewegt, so dass der Klingenträger 12 über die Schneidposition hinweg in eine Klingenwechselposition (siehe die Fig. 4 und 5) bewegbar ist, indem die Handhabe in die Endposition bewegt wird. Bei dem vorliegenden Ausführungsbeispiel verhindert eine Sicherungsvorrichtung, dass sich der Riegel 15 in die Freigabeposition bewegen kann, wenn der Klingenträger 12 in der Schneidposition angeordnet ist. In der Klingenwechselposition des Klingenträgers 12 kann der Riegel 15 nicht in Richtung w2 in die Sperrposition geschwenkt werden.In the locked position, the first stop 14 is in the movement path of the blade carrier 12. The first stop 14 therefore defines the cutting position of the blade carrier 12 when it is arranged in the locked position. In the release position, the first stop 14 is moved out of the movement path of the blade carrier 12, so that the blade carrier 12 moves into a blade changing position beyond the cutting position (see FIG 4 and 5 ) is movable by moving the handle into the end position. In the present exemplary embodiment, a securing device prevents the bolt 15 from being able to move into the release position when the blade carrier 12 is arranged in the cutting position. In the blade changing position of the blade carrier 12, the latch 15 cannot be pivoted in the locking position in the direction w2.

Eine Arretierung 16 ist verschiebbar an dem Gehäuse 11 gelagert und ist zwischen einer Riegelposition (siehe die Fig. 1 und 5) und einer Löseposition (siehe die Fig. 2, 3, 4 und 6) bewegbar. Befindet sich die Handhabe 13 in der Endposition und der Klingenträger 12 ist in der Klingenwechselposition angeordnet, dann kann die Handhabe 13 verriegelt werden, in dem die Arretierung 16 in die Riegelposition bewegt wird. In der Riegelposition greift ein Fortsatz 18 der Arretierung 16 formschlüssig in eine Aussparung 19 der Handhabe 13 wodurch eine Bewegung der Handhabe 13 verhindert wird. Ein Klingenwechsel kann daher durchgeführt werden, ohne dass die Handhabe entgegen der Rückstellkraft der Rückstellvorrichtung in der Endposition gehalten werden muss.A lock 16 is slidably mounted on the housing 11 and is between a locking position (see the Fig. 1 and 5 ) and a release position (see the 2, 3 . 4 and 6 ) movable. If the handle 13 is in the end position and the blade carrier 12 is arranged in the blade changing position, then the handle 13 can be locked by moving the locking device 16 into the locking position. In the locking position, an extension 18 of the locking device 16 engages positively in a recess 19 in the handle 13, thereby preventing the handle 13 from moving. A blade change can therefore be carried out without having to hold the handle in the end position against the restoring force of the restoring device.

In der unbetätigten Position der Handhabe 13 ist die Arretierung 16 ebenfalls in die Riegelposition bewegbar. Der Fortsatz 18 greift dann formschlüssig in eine Aussparung 20 der Handhabe 13. Der Klingenträger 12 kann sich nicht aus der Sicherheitsposition herausbewegen und die Handhabe 13 lässt sich nicht aus der unbetätigten Position heraus bewegen, wenn sich die Arretierung in der Riegelposition in Eingriff mit der Aussparung 20 befindet.In the unactuated position of the handle 13, the lock 16 can also be moved into the locking position. The extension 18 then engages positively into a recess 20 of the handle 13. The blade carrier 12 cannot move out of the safety position and the handle 13 cannot be moved out of the unactuated position when the locking means is in engagement with the recess 20 in the locking position.

Gemäß Fig. 1 befindet sich die Handhabe 13 in der unbetätigten Position und die Arretierung 16 ist in der Riegelposition angeordnet. Der erste Anschlag befindet sich in der Sperrposition.According to Fig. 1 the handle 13 is in the unactuated position and the lock 16 is arranged in the locking position. The first stop is in the locked position.

Zur Inbetriebnahme des Messers 10 aus dem Zustand gemäß Fig. 1 wird die Arretierung 16 in Richtung x1 in die Löseposition bewegt (siehe Fig. 2). Die Handhabe 13 kann dann in die betätigte Position gemäß Fig. 3 bewegt werden, in welcher der Klingenträger 12 in Richtung y1 in die Schneidposition bewegt ist und an dem ersten Anschlag 14 anliegt. In der Schneidposition des Klingenträgers 12 ist der Riegel 15 nicht in die Freigabeposition schwenkbar. Wird die Handhabe 13 nicht mehr betätigt, so bewegt die Rückstellvorrichtung den Klingenträger 12 in Richtung y2 in die Sicherheitsposition und die Handhabe 13 in Richtung u2 in die unbetätigte Position.To start up the knife 10 from the state according to Fig. 1 the lock 16 is moved in the x1 direction to the release position (see Fig. 2 ). The handle 13 can then according to the actuated position Fig. 3 are moved, in which the blade carrier 12 is moved in the direction y1 into the cutting position and abuts the first stop 14. In the cutting position of the blade carrier 12, the latch 15 cannot be pivoted into the release position. If the handle 13 is no longer actuated, the reset device moves the blade carrier 12 in the direction y2 into the safety position and the handle 13 in the direction u2 into the unactuated position.

Soll ein Klingenwechsel durchgeführt werden, so ist ausgehend von dem Zustand des Messers 10 gemäß der Fig. 1 und 2 die Arretierung 16 in Richtung x1 in die Löseposition zu bewegen und der Riegel 15 in Richtung w1 in die Freigabeposition zu verstellen. Die Handhabe 13 kann dann in die Endposition bewegt werden, wobei der Klingenträger 12 in Richtung y1 in die Klingenwechselposition bewegt wird. Die Klingenwechselposition ist in Fig. 4 dargestellt. In der Endposition der Handhabe 13 (siehe Fig. 4) wird die Arretierung 16 in Richtung x2 in die Riegelposition bewegt (siehe Fig. 5). Die Handhabe 13 verbleibt dann in der Endposition und der Klingenträger 12 in der Klingenwechselposition, ohne dass der Benutzer die Handhabe 13 entgegen der Rückstellkraft der Rückstellvorrichtung betätigen muss. Ein Klingenwechsel ist nun einfach durchführbar.If a blade change is to be carried out, the state of the knife 10 according to FIG 1 and 2 to move the locking device 16 in the direction x1 to the release position and to move the bolt 15 in the direction w1 to the release position. The handle 13 can then be moved into the end position, the blade carrier 12 being moved in the direction y1 into the blade changing position. The blade change position is in Fig. 4 shown. In the end position of the handle 13 (see Fig. 4 ) the locking mechanism 16 is moved in the direction x2 into the locking position (see Fig. 5 ). The handle 13 then remains in the end position and the blade carrier 12 in the blade change position without the user having to use the handle 13 against the restoring force of the Must reset device. It is now easy to change the blade.

Um das Messer ausgehend von der Klingenwechselposition wieder in den Zustand gemäß Fig. 2 zu versetzen, wird der Arretierung 16 in Richtung x1 in die Löseposition bewegt. Von die Rückstellvorrichtung wird dann die Handhabe 13 in Richtung u2 in die unbetätigte Position und der Klingenträger 12 in Richtung y2 in die Sicherheitsposition bewegt (siehe Fig. 6). In der Sicherheitsposition gemäß Fig. 6 kann der Riegel 15 in Richtung w2 in die Sperrposition geschwenkt werden (siehe Fig. 2).To return the knife to the state it was in, starting from the blade change position Fig. 2 to move, the lock 16 is moved in the direction x1 to the release position. The reset device then moves the handle 13 in the u2 direction to the unactuated position and the blade carrier 12 in the y2 direction to the safety position (see Fig. 6 ). In the security position according to Fig. 6 the latch 15 can be pivoted in the locking position in the direction w2 (see Fig. 2 ).
